Zeziphi iindidi zee-eriyali ezikhoyo?

 I-Antenna Category

I-eriyali sisixhobo esisasaza iisignali zamaza erediyo ukusuka kwintambo yothumelo ukuya emoyeni okanye siyifumana emoyeni isiya kwintambo yothumelo.Inokuthi ithathwe njengenguqu ye-impedance okanye isiguquli samandla.Guqula ibe ngamaza e-electromagnetic asasazeke kwindawo engenamida, okanye ngokuphendululekileyo.Kuyilo lwesixhobo se-transceiver esingenazingcingo esisetyenziswe kwinkqubo yerediyo yerediyo, uyilo kunye nokukhethwa kwe-eriyali yinxalenye ebalulekileyo yalo.Inkqubo ye-antenna elungileyo inokufezekisa umgama wonxibelelwano.Ubungakanani bohlobo olufanayo lwe-eriyali ilingana nobude bezandi zesiginali yefrikhwensi yerediyo.Okukhona kusezantsi i-frequency, kokukhona i-eriyali ifuna ukuba nkulu.

Ii-eriyali zinokwahlulwa zibe zii-eriyali zangaphandle kunye nee-eriyali ezakhelwe ngaphakathi ngokwendawo yokufakela.Ezo zifakwe ngaphakathi kwesi sixhobo kuthiwa zii-eriyali ezakhelwe ngaphakathi, yaye ezo zifakwe ngaphandle kwesixhobo zibizwa ngokuba zii-eriyali zangaphandle.Kwiimveliso ezinobungakanani obuncinci njengezixhobo eziphathwayo, uyilo olunxibekayo, kunye namakhaya ahlakaniphile, ii-eriyali ezakhelwe ngaphakathi zisetyenziswa ngokuqhelekileyo, kunye nokudibanisa okuphezulu kunye nenkangeleko enhle.I-Intanethi yezinto kunye neemveliso ze-smart hardware kufuneka zigqithise idatha kwi-intanethi, ngoko ke zonke kufuneka zisebenzise i-eriyali.

Isithuba esincinci kunye neebhendi zefrikhwensi, kokukhona intsonkothileyo uyilo lwe-eriyali.Ii-eriyali zangaphandle ziyimveliso eqhelekileyo.Ungasebenzisa ii-eriyali kwiibhendi zamaza ezifunekayo ngaphandle kokulungiswa kweempazamo, iplagi nje kwaye udlale.Umzekelo, iikhabhathi ezicacileyo, oomatshini bokuthengisa, njl.njl., ngokubanzi basebenzisa ii-eriyali zangaphandle ezinomagnetic, ezinokufunxwa kwiqokobhe lentsimbi.Ezi-eriyali azikwazi ukufakwa kwikhabhinethi yentsimbi, kwaye isinyithi siya kukhusela umqondiso we-eriyali, ngoko ke zinokubekwa ngaphandle kuphela.Eli nqaku ligxininise kwindlela yokwahlula kunye nokukhethwa kwe-antenna, kwaye ikwazisa ulwazi olufanelekileyo lwe-antenna.

1. I-Antenna yangaphandle 

Ii-eriyali zangaphandle zinokwahlulwa zibe zii-eriyali ze-omnidirectional kunye ne-eriyali eyalathiswayo ngokweengile ezahlukeneyo zemitha yelanga lemitha.

i-eriyali ye-omnidirectional

Ii-eriyali ze-Omnidirectional, oko kukuthi, imitha ye-360 ° efanayo kwipatheni ethe tye, oko kukuthi, into ebizwa ngokuba yi-non-directional, kunye nomqadi onobubanzi obuthile kwipatheni ethe nkqo.Ngokubanzi, incinci ububanzi belobe, Inzuzo enkulu.

I-eriyali yomkhombandlela

I-eriyali eyalathayo ibhekisa kwi-eriyali ethumela kwaye ifumane amaza ombane kwicala elinye okanye iindlela ezininzi ezithile ezinamandla ngakumbi, ngelixa ukusasaza kunye nokufumana amaza ombane wombane kwamanye amacala kunguziro okanye kuncinci kakhulu.Injongo yokusebenzisa i-eriyali yokuhambisa i-directional kukunyusa ukusetyenziswa okusebenzayo kwamandla ombane kunye nokwandisa imfihlo;eyona njongo iphambili yokusebenzisa i-eriyali yokufumana i-directional kukuphucula amandla omqondiso kunye nokwandisa amandla okuchasana nokuphazamiseka.Ii-eriyali zecala langaphandle ikakhulu ziquka ii-eriyali zephaneli ezisicaba, ii-eriyali zeYagi kunye ne-logarithmic periodic eriyali.

2.I-eriyali eyakhelweyo

 I-eriyali eFakelweyo ibhekisa ikakhulu kwigama eliqhelekileyo lee-eriyali ezinokufakwa ngaphakathi kwesixhobo.Ii-eriyali ezakhelwe ngaphakathi ikakhulu ziquka ii-eriyali ze-FPC, ii-eriyali ze-PCB, i-eriyali zasentwasahlobo, ii-eriyali ze-ceramic patch, i-laser direct structuring (LDS) kunye nee-eriyali ze-shrapnel zentsimbi.

• Xa ukhetha i-antenna efanelekileyo kwisixhobo, okokuqala, kuyimfuneko ukugqiba ukuba ukhethe i-antenna yangaphakathi okanye yangaphandle ngokwesakhiwo semveliso.I-eriyali yangaphandle kukufaka i-eriyali ngaphandle kwesixhobo;
• i-eriyali yangaphandle
• Inzuzo ephezulu;
• Ayichatshazelwa kangako yimekobume, ingasetyenziswa njengemveliso eqhelekileyo, kwaye igcina imijikelo yophuhliso;
• Thatha indawo kwaye uchaphazele ukubonakala kweemveliso.
• I-eriyali eyakhelweyo •
• Inzuzo ephezulu kakhulu;
• Itekhnoloji evuthiweyo kunye nokungaguquguquki kokuhanjiswa kwemveliso;
• Yakhelwe kwisixhobo, esihle, akukho mfuneko yokwenza izinto ezintathu zokukhusela ngokwahlukeneyo;
• Ichaphazeleka kakhulu yimeko engqongileyo kwaye ngokubanzi ifuna ukulungiswa ngokudibanisa nemveliso ngokwayo.
